11. (5 marks) Two customers, Bob and Mary, arrive at an occupied service counter at the same time. Bob insists Mary go ahead of him. Let X denote the time (in minutes) until Mary can be served and Y be the time (in minutes) until Bob is served. Suppose the joint density of X and Y is f(x, y) 0 , otherwise Find the moment-generating function of U --aln(X/Y). What is the distribution of U?

13. (5 marks) In order for a device to run, two batteries must both be functional. Let X be the lifetime of battery 1, and Y be the lifetime of battery 2, both measured in days. Suppose the joint density of X and Y is given as f(x, y)-po 0 , otherwise If you just turned on the device with these new batteries, what is the expected life of the machine? That is, what the expected time to wait until...

Using the book, write another paragraph or two: write 170
words:
Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
